Radiologic Findings


T1- and T2-weighted magnetic resonance (MR) images (Fig. 143.1) reveal the presence of an ovoid mass adjacent to the left external iliac vessels. The mass is hypointense on the T1-weighted image and hyperintense on the T2-weighted image.


Diagnosis


Undescended testis (cryptorchidism)


Differential Diagnosis



  • Enlarged external iliac lymph node
  • Aneurysm of the left external iliac artery
  • Soft tissue mesenchymal tumor

Discussion


Background


Cryptorchidism means “hidden or obscure testis” and generally refers to an undescended or maldescended testis. Although 4% of newborns have undescended testes, the incidence falls to 0.8% by 3 months, as the testis may spontaneously descend after birth.
